Anthurium plant named ‘Anthzupap’

ABSTRACT

A new  Anthurium  plant particularly distinguished by having glossy orange-red, durable spathes that slowly turn brown with age, dark green, durable leaves, an erect penduncle, rich shoot formation, flowers continuously throughout the year, a compact and full plant habit and a plant height of 35.0 cm to 45.0 cm, is disclosed.

Genus and species: Anthurium andreanum L.

Variety denomination: ‘Anthzupap’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of Anthurium, botanically known as Anthurium andreanum L., and hereinafter referred to by the variety name ‘Anthzupap’. The new variety originated from a hybridization made in April 2002 in Bleiswijk, The Netherlands. The female parent was a dark red Anthurium pot plant ‘4431-01’ (unpatented), while the male parent was a red Anthurium plant ‘4462-07’ (unpatented).

A single plant was selected in February 2004 and has been asexually reproduced repeatedly by tissue culture in Bleiswijk, The Netherlands over a five-year period. The new variety has been found to retain its distinctive characteristics through successive asexual propagations.

Plant Breeder's Rights for this variety were applied for in the European Union on Dec. 8, 2008 and in Japan on Mar. 9, 2010. ‘Anthzupap’ has not been made publicly available more than one year prior to the filing of this application.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of this new variety when grown under normal horticultural practices in Bleiswijk, The Netherlands.

-   -   1) An orange-red colored medium sized glossy spathe;     -   2) White spadix;     -   3) Rich shoot formation;     -   4) Compact plant habit; and     -   5) Dark green foliage.

DESCRIPTION OF THE PHOTOGRAPHS

This new Anthurium plant is illustrated by the accompanying photographs; the colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs are of a 48-week old plant grown in a greenhouse in Bleiswijk, The Netherlands in 2009.

FIG. 1 shows the overall plant habit, including blooms, buds and foliage.

FIG. 2 is a close-up of the mature spathe.

FIG. 3 shows three spathes at different stages of development.

FIG. 4 shows the upper and lower leaf surfaces.

DESCRIPTION OF THE NEW VARIETY

The following detailed description sets forth the distinctive characteristics of ‘Anthzupap’. The data which define these characteristics were collected from asexual reproductions carried out in Bleiswijk, The Netherlands. The plant history was taken on 48-week old plants which were planted from tissue culture in 17 centimeter pots and grown in a glass greenhouse between 19° C. and 24° C. Observations were made in November of 2009. Color readings were taken under 5000 lux natural light in the greenhouse. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) (2001).

At 7 to 8 weeks after opening: The upper             surface becomes RHS 45A, slowly turning brown (approximately             RHS 181A) towards the lobes. At 14 to 16 weeks after             opening: The color slowly turns brown completely originating             from the lobes towards the tip.

More blossoms appear             after some additional weeks so that a full flowering and             commercial plant will have 6 to 10 orange red spathes.

Width (at base): 0.5 cm             to 0.8 cm.         -   Shape.—Columnar.         -   Angle of spadix tip with peduncle.—180 degrees (spadix is in             one line with peduncle).         -   Texture.—When the spathe is unfurling the spadix is smooth.             When the spadix matures, very small stigmata protrude. The             stigmata are evenly distributed round the spadix. The spadix             matures from base to top, slowly giving the spadix a             somewhat rough appearance.         -   Color.—Immature: RHS 15A. Mature: RHS 155A.

‘Anthzupap’ differs from the female parent ‘4431-01’ (unpatented) by having orange-red spathes, whereas ‘4431-01’ has dark red spathes.

‘Anthzupap’ differs from the male parent ‘4462-07’ (unpatented), by having orange-red spathes, whereas ‘4462-07’ has red spathes.

‘Anthzupap’ is comparable to commercially available varieties ‘Anthuci’ and ‘Anthabazal’. ‘Anthzupap’ differs from ‘Anthuci’ in that ‘Anthzupap’ has slight spathe blistering, while ‘Anthuci’ has strong spathe blistering.
